ANNEX II Harmonised efficiency reference values for separate production of heat (referred to in Article 1) In the table below the harmonised efficiency reference values for separate production of heat are based on net calorific value and standard atmospheric ISO conditions (15 °C ambient temperature, 1,013 bar, 60 % relative humidity).
